I live in San Antonio, Texas so the temps are way hotter. With your chart and temps between 95-100 every day it says i would need to reapply in like 10 days. Does that sound right?

@MidwestLawnGoals-in2gv Ай бұрын

Sorry for the delay in response, I had to figure my own stuff out. I’m experiencing the same conundrum as many of you with this GDD calculation. The GDD formula works great if the temps are within the growing rage. When we start pushing into the summer with the high temps, I have learned that I need to adjust a bit. Let me explain, the base temp used in the GDD is basically the minimum temp at which the plant starts growing. The issue I experienced is with the high temps during the day, I was calculating very large GDDs, causing me to apply the PGR far to regularly. After reading a few studies, I found that farmers adjust their max temps based on the crop. I know that my max growing temp for my perennial rye is 87 F, so when my temps go over that number, I use 87 F as my max temps. Example, let’s say the today’s temp range is 97 F - 66 F. Using what I know now, the temps I enter in my GDD calculator will be 87 instead of 97 which will give me a far lower GDD number. Currently, with the temps rising and fluctuating in the Midwest, I have been getting away with a 350 GDD instead of the 280 GDD I used in fall. Now, everything I just talked about was for perennial rye, so you will have to determine the growing temp range for your own grass type. This is working for me now based on grass I’m colleting when mowing. Good luck!

Im going to go 1/2 rate every 2 weeks to keep it simple. Its Bermuda, it wont die

@MidwestLawnGoals-in2gv 4 сағат бұрын

That sounds about right for summer. In my area as the weather gets colder I can stretch that out to every 4 weeks. Going to try Monaco Bermuda spring 2025! Cheers!

@@MidwestLawnGoals-in2gv good luck!!!! I just seeded 11,500 sq ft of Monaco 13 weeks ago, had my very very best seeding when I pre germinated until I saw many roots shoot then mixed with humichar, I seeded 3 different times, thunderstorms lol the longer I kept the seeds wet the better. This grass is dark green lol

One Question. In row 27, because you have a negative, you lost a couple GGD's. Is that correct? All other calculators I've seen treat a negative as a "0" instead of subtracting GGD's. Probably not a big deal but just curious.

@MidwestLawnGoals-in2gv 4 ай бұрын

That is correct, anything in the negative I zero out that GDD. Basically I just move the previous positive GDD down so it does not mess with the formula. Now, even if the GDD is 0.1 it’s positive so I still keep it. Have a great growing season! I’m dealing with some ridiculous tnex rebound right now with the warmer than normal temps this month.

What website shows us when to apply PGR?

@MidwestLawnGoals-in2gv 3 ай бұрын

I believe the most popular one is greencastonline.com. It will give you the GDD but you still have to add it up yourself based on when you applied it. If you have questions on how I did my tracking contact me through my email and I can do a 1 on 1 walkthrough with you. Cheers!

I live in North Carolina. Going by ACC GDD, I would have to apply every week (approximately). This appears to be PGR OVERKILL. Are you sure this method is accurate?

@joshuawrye Ай бұрын

TLDR version of below: It completely depends on what type of grass you have for the base (warm = 10 / cool = 0), it's cut height for product volume (shorter = lower rate), and the observed air temperature for lifespan (max - min) depending on the grass. If all else fails, error on the side of caution by starting out using a lower rate until you see how your lawn reacts, then up the rates depending on response (I NEVER go to max rate). Most liquid PGRs I've used can be applied every 7 days at it's lower rate. Couple things to consider: First make sure you are accounting for cut height and type of grass. Warm season grasses use base 10 while cool season uses base 0. The higher you cut, the longer the lifespan of the application. Kentucky 31 cut at 2.5-3.5 inches would have a lifespan of 320-350 Celsius (base 0), while Bermuda cut at 1-1.5 inches would have a lifespan of 225 (base 10). My front yard is Bermuda while my back yard is K31 (where the kids play, front yard is just for show). When my Bermuda is in it's prime growth stage, it can go for 2 weeks between applications, while my K31 needs an application every 7-9 days when it's at it's peak growth. To augment this, during spring and fall, I cut my K31 shorter to raise that lifespan up a bit and I can get away with every other week.

Why "-0"?

@joshuawrye Ай бұрын

When you are using a cool season grass your base is 0, but if you are using a warm season grass your base is 10. So a warm season grass would subtract 10, while a cool season grass subtracts nothing.
